July 13, 1882.] JOURNAL OF HORTICULTURE AND COTTAGE GARDENER. 39 
full. The half-expanded buds were particularly beautiful both in 
form and colour. 
Tuberous Begonia A. F. Barron (Royal Horticultural Society).— 
A handsome variety, with large bright scarlet flowers 3J inches in 
diameter, the petals very round,' broad, and bright in colour. The 
foliage is very dark green, and the habit compact. 
Scientific Committee. —Dr. M. T. Masters in the chair. 
Hollyhock Disease. —Mr. W. G. Smith exhibited specimens of fruits 
of the common Mallow with Puccinia Malvacearum. They were sent 
by Mr. Phillips, who gathered them near Shrewsbury. Their fruits 
confirmed the correctness of Mr. Smith’s observation—that the fungus- 
infected fruits or seeds of the Malvaceae fall to the ground, and are 
then capable of producing seedlings diseased with Uredo spores with¬ 
out an intervening iEcidium condition. 
Hart's-tongue Fern Diseased. —He also showed a specimen of this 
Fern attacked by Didymium effusum, Lk., new to Great Britain. 
It occurs on both sides of the frond, and grows over the ruptured 
masses of spore cases (sori), and even amongst the free spores. 
Dwarf Oak. —Dr. Masters exhibited a spray of a dwarf Oak, Quercus 
eucine (humilis), from South Spain. It never attains a height over 
2 feet. It was in full fruit. 
Oat and Clematis roots attacked with vibrio were also shown by him. 
It appears to be one variety only of black Oat which is affected, and 
that to such an extent as to destroy whole crops year after year. 
Gardenia and Petroleum. —He exhibited a spray of Gardenia treated 
with petroleum oil and water (a wineglass to a gallon) for killing 
mealy bug, showing the very healthy character of the plant. 
Thuja japonica (Standishii). — Dr. Masters showed specimens in 
fruit. 
Water Lily with Foliaceous Sepal. —He also showed a specimen in 
which a leaf blade had developed on the apex of a sepal, proving that 
the sepal, as is usually the case, is a petiole only. 
Coloured Pea Pods. —Mr. Laxton sent pods of purple and white 
Peas, as well as pods of the former crossed by the latter, with purple 
and green intermixed. From examination it appears that the purple 
colour overlies the chlorophyll. 
Antirrhinum Hendersoni. —Mr. Cannell exhibited flowers of this 
race, white with a narrow crimson border to the petals. It is an old 
form but rarely seen, as it will not set seed, this being apparently 
due to atrophy of the essential organs. 
Aerial Tubers of Potato. —The Rev. G. Henslow exhibited tubers 
found in the axils of leaves. 
Canker in Pears. —These were received from Daventry, where it 
appears very prevalent; the cause was unknown. 
Plants Exhibited. —Sedum Semluovii, from the Caucasus, by Dr. 
Masters. Hoya lasiantha having hairy petals, from Borneo, by 
Messrs. Yeitch, as well as Impatiens Sultani, with crimson flowers, 
from Zanzibar ; as also a curious Aroid, Lasia stipitata, from Borneo. 
These three received botanical certificates. Hesperaloe yuccaefolia, 
from California, which had been flowering ever since June, 1881, was 
also sent by the same gentleman. 
At a meeting of the Fruit and Floral Committees at Chiswick on 
July the 7th certificates were awarded for the following vegetables

THE PEAR TREE SLUG—FRUIT IN NEW 
ZEALAND. 
I WAS much interested by your reply to a correspondent in re¬ 
ference to this insect. I do not recollect having ever noticed it in 
this country, but last January whilst in New Zealand I w r as quite 
astonished at the ravages wrought by it at Nelson. The Pear 
trees there suffered badly, but the Cherries far more so, and I do 
recollect seeing one Cherry tree that had not had its leaves 
almost entirely devoured by this insect, which they there call a 
leech, and which answers exactly the description you give. The 
quick hedges also suffered quite as much as the Cherry trees 
from this pest, though Apricots, Apples, Plums, &c., seemed 
unmolested.
